  • Publication number: 20240047547
    Abstract: A semiconductor device includes a source via having a body portion and a barrier layer surrounding the body portion, and the body portion is in physical contact with the source contact. Furthermore, the barrier layer includes at least one sidewall section separating the source via from an adjacent via structure. As such, the via to via leakage may be prevented. Overall, by providing a semiconductor device having the above structures, the contact resistance is reduced, and the device performance is further improved.

  • Publication number: 20230317858
    Abstract: A method and device according to the present disclosure includes a substrate that has a first transistor terminal such as a source feature and a second transistor terminal such as another source feature. Contact structures are formed on each source/drain feature. After forming the contact structures, a via opening is formed in dielectric materials above the contact structures, which is filled to form a non-linear via that extends from the contact on the first source feature to the contact on the second source feature. The non-linear via may include an outline in a top view of an undulating-shape having convex and/or concave portions.

  • Publication number: 20230260796
    Abstract: In a method of manufacturing a semiconductor device, an initial pattern layout is obtained. The initial pattern layout incudes fin patterns which include active fin patterns to be formed as active fin structures and dummy fin patterns not to be formed as actual fin structures or to be removed. The locations of the fin patterns are modified, as follows. A space between adjacent active fin patterns is increased by a first amount, a space between the dummy fin patterns is decreased by a second amount, and a space between one of the dummy fin patterns and one of the active fin patterns adjacent to the one of the dummy fin patterns is decreased by a third amount. Mandrel patterns are placed so that the fin patterns of which locations are modified are placed along longitudinal edges of the mandrel patterns.
